Problems solved by technology

In actual production, for different agronomy, it is necessary to adjust the sowing rate and fertilization rate when sowing. The existing planter mainly adjusts the sowing rate by replacing the seeding tray with different hole numbers, which is inconvenient to use and time-consuming and labor-intensive. In addition, Once the direction of the seeding disc in the seeder on the planter is determined, it is difficult to change, and there is no device that can prevent the seeding disc from reversing when the seeding unit is reversed

Abstract

The invention belongs to the technical field of seed-sowing machines, and relates to an adjusting device for variables of a seed-sowing machine combining seeding and fertilizing. The seed-sowing machine comprises a box body combination, an input shaft combination, a transmission shaft combination, an output shaft combination and an adjusting handle, wherein when the adjusting device for variables works, the input shaft chain wheel transmits power to the input shaft, so that the driving chain wheel is driven, the power of the input shaft is transmitted to a driven chain wheel to drive a positioning sleeve and a chain combination wheel; the chain combination wheel can be meshed with one of the low-gear chain wheel, the middle-gear chain wheel and the high-gear chain wheel by inserting the adjusting handle into a preset positioning pore plate, so that the power is transmitted to the output shaft, speed regulation and direction change can be realized, and the output shaft drives the transcend clutch and the output chain wheel to rotate. The adjusting device for variables is simple in structure, and can satisfy the requirement of a planter plate on direction change, and prevent the unit from reversing during setback, which causes seed breakage.

Description

technical field [0001] The invention belongs to the technical field of seeders in agricultural machinery, and in particular relates to a seeder variable adjustment device for sowing and fertilization linkage, which is used for variable sowing and fertilization of rapeseed, wheat and other crops, and can change the direction of the input shaft to prevent the seeding unit from reversing. The seed disc is reversed. Background technique [0002] At present, the power of the seed and fertilizer discharge devices of domestic sowing operation tools mainly comes from the ground wheel. In actual production, for different agronomy, it is necessary to adjust the sowing rate and fertilization rate when sowing. The existing planter mainly adjusts the sowing rate by replacing the seeding tray with different hole numbers, which is inconvenient to use and time-consuming and labor-intensive. In addition, Once the turning direction of the seeding disk in the seed metering device on the seede...
